We investigate theories in which the technifermions in higher dimensional representations of the technicolor gauge group dynamically break the electroweak symmetry of the standard model. Somewhat surprisingly, for the two-index symmetric representation of the gauge group the lowest number of techniflavors needed to render the underlying gauge theory quasiconformal is two. This is exactly one doublet of technifermions with respect to the weak interactions promoting these theories to ideal…

Discovering Technicolor

We provide a pedagogical introduction to extensions of the Standard Model in which the Higgs is composite. These extensions are known as models of dynamical electroweak symmetry breaking or, in

Mass enhancement and critical behavior in technicolor theories.

This paper investigates the properties of composite scalars made mainly of technifermions and finds that for realistic values of the gauge coupling, the scalars will not be narrow resonances, and concludes that unless the technicolor coupling at the E TC scale is unrealistically weak and the ETC coupling is very close to the critical curve, these light states will have large widths.

Invisible Technicolor

We propose a scenario of dynamical electroweak symmetry breaking which is applicable to the model with no tree-level potential for the elementary Higgs doublet field. An example of such a model is the

We present an economical theory of natural electroweak symmetry breaking, generalizing an approach based on deconstruction. This theory is the smallest extension of the Standard Model to date that

We show that it is possible to construct explicit models of electroweak symmetry breaking in which the number of techniflavors needed to enter the conformal phase of the theory is small and weakly

Recently a new class of theories of electroweak symmetry breaking have been constructed. These models, based on deconstruction and the physics of theory space, provide the first alternative to

Low energy strong electroweak sector with decoupling.

It is conceivable that degenerate BESS has low mass spin-one states and gives quite visible signals at existing or forthcoming accelerators, and it is worthwhile to fully develop the model, together with its possible generalizations, and to study the expected phenomenology.
